Next: Problems of Fourier Up: Some Problems of Practical Previous: To Restore or . Photometry of restored images has two problems. First, many restorations are photometrically unfaithful, and you get the wrong answer. ... And of course there are situations where it is absolutely necessary to restore the image. ... We ran the lucy task that is in STSDAS, for the usual 80 iterations, and it gave the wrong answer; the ratio of the heights of the two peaks was wrong by about 10 or 20%. ...

... User Guide ] Task: early Purpose: Flag data which has early/normal problems. Categories: calibration, uv analysis EARLY is a Miriad task which flags visibility data that it suspects contains early/normal problems. ... If the scatter exceeds some number of sigmas, then the data are assumed to be affected by the early/normal problem, and the entire record is flagged. ... If the signal is noise dominated, no early/normal problems can be detected, and the data will not be flagged. ...

Telescope Jumps: One Cause is Found . ... One tries to take out the sag of the secondary cage as the telescope is pointed toward the zenith. The second component tries to take out changes in the secondary piston caused by temperature changes of the truss structure. ... Second, the jumps only occur when the temperature data causes motions of the piston which go in a direction opposite to the direction in which the sag component is driving the secondary. ... One has to wonder how this can occur. ...

... The RCB carbon abundance remains an enigma ([ Asplund et al. ... The strength of a stellar absorption line represents the ratio of line opacity to continuous opacity in the atmosphere; both are related to the number density of the absorbing atoms and so provide the number ratio of line absorbers to continuum absorbers. ... Since the predominant continuum absorber in RCB atmospheres is neutral carbon, it has not yet proved possible to measure the carbon abundance from carbon absorption lines. ...
